Creating animated GIF from vector data

Inspired by Johannes Uhl's shapefile2gif, I created a vector_to_gif() function in leafmap that makes it much easier to create animated GIF from vector data with only one line of code. The sample dataset used in this notebook is a subset of the dataset retrieved from the shapefile2gif repo. Credits to Johannes Uhl. For more information about the datasets, check out the references below:
